Used Behringer HA400 Pro Sound Product

Compact and studio friendly, the Behringer HA400 Microamp is a four channel headphone amplifier built for sharing a single audio source without sacrificing clarity. Each output has its own dedicated level control, making it easy to tailor volume for multiple listeners at once, whether it is a rehearsal, tracking session, or late night practice setup. The metal chassis keeps things solid while the simple layout makes it plug and play.

Designed to deliver clean signal with plenty of headroom, the HA400 is known for low noise operation and consistent output across all channels. Its ability to drive multiple sets of headphones simultaneously makes it a staple in home studios, teaching setups, and band practices where clear monitoring matters. Behringer designed this unit to be straightforward and reliable, focusing on sound quality and practicality rather than unnecessary extras.

This unit has been fully tested in store and is working as it should, with a power supply included. We buy, sell, and trade used gear every day, so if you are looking to refresh your setup or move something along, we can help with that too.
